Swift is a multi-wavelength space observatory dedicated to the study of gamma-ray burst science. Swift is part of NASA's Medium-class Explorer (MIDEX) mission which was launched in 2004. Swift has three co-aligned instruments on board: a Burst Alert Telescope (BAT), an X-ray telescope (XRT) and an ultraviolet/optical telescope (UVOT). These instruments work together to observe gamma-ray bursts and afterglows in the gamma-ray, X-ray, optical, and ultraviolet wavebands.
